By the way that the second heat regulation portion (heat pump unit) is arranged, slurry temperature is on the one hand reduced, keeps flue gas empty in reaction
Interior is not only to absorb its cooling by the moisture evaporation in slurries and release heat, and the loop slurry of big flow is reacting
Heating similarly absorbs its cooling and releases heat in space, to reduce water evaporation quantity, reaches water-saving purpose；Another party
Face, slurries have transferred heat to the first heat transferring medium by heat pump unit, so that further heating of having the ability improves smoke evacuation
Temperature.
In addition, solving by heat pump unit since slurry temperature is lower, general heat exchanger must have heat-exchange temperature end
Difference, it is difficult to heat is therefrom obtained, even if obtaining heat by cryogenic media, because of its temperature too low the problem of being also difficult to be utilized.
Heat transfer sufficiently can be obtained to the first heat transferring medium from slurries, the temperature of the first heat transferring medium can be higher than slurry temperature.
